【摘要】 对贵州水城沙坡试验区土壤的调查结果表明,土地利用方式对土壤理化性质有较大影响,即林地、果园等土地利用强度较小的植被条件下,土壤养分含量高,理化性质好;开垦后,土地利用强度较大的耕地土壤理化性质变化大,土壤养分含量较差。更多还原

【Abstract】 The soil physical properties and chemistry characteristic had been studied in survey of Shapo village. The result showed that the soil physico-chemical properties are effected by different soil utilization types. The soil nutrient content and physico-chemical properties of the wood and orchard land are better than those of the arable land, which is intensively utilized.更多还原
